Types :-

1. Pyogenic Liver Abscess :- Caused by bacterial infections.
2. Amoebic Liver Abscess :- Caused by Entamoeba histolytica, the parasite responsible for amoebiasis.
3. Fungal Liver Abscess :- Caused by fungal infections, less common.

Causes :-

• Pyogenic Abscess :- Often results from infections originating from the bile ducts, the bloodstream, or nearby organs (e.g., appendicitis or diverticulitis).
• Amoebic Abscess :- Typically arises from amoebic dysentery, which can spread to the liver via the bloodstream.
• Fungal Abscess :- Typically seen in immunocompromised individuals.

Symptoms :-

• Fever and chills
• Abdominal pain, particularly in the upper right quadrant
• Nausea and vomiting
• Loss of appetite
• Weight loss
• Jaundice (in some cases)
• General malaise

Diagnosis :-

• Imaging Tests :- Ultrasound, CT scan, and MRI to visualize the abscess and assess its size and location.
• Blood Tests :- To identify infection markers and liver function.
• Liver Aspiration :- Using a needle to aspirate pus from the abscess for analysis, including culture and sensitivity testing.

Treatment :-

• Antibiotics :- For bacterial infections.
• Antiparasitic Medication :- For amoebic liver abscesses (e.g., metronidazole).
• Antifungal Medication :- For fungal abscesses.
• Surgical Drainage :- In some cases, especially if the abscess is large or not responding to medication.
• Percutaneous Drainage :- Using imaging guidance to insert a catheter to drain the abscess.

Complications :-

• Sepsis :- Systemic infection that can be life-threatening.
• Biliary Obstruction :- Can result from infection spreading to bile ducts.
• Liver Failure :- In severe or untreated cases.

Prognosis :-

• With appropriate treatment, the prognosis is generally good. Early diagnosis and treatment are crucial for preventing serious complications.
